BOAT BAILER Sigrid T. Larsen, Minneapolis, Minn.

Application August 15, 1941, Serial No. 407,078

1 Claim.

My invention relates to boat bailers and has for its object to provide an implement to be used in the hand which will efficiently scoop up the water in the bottom of a boat such as a rowboat and with one movement of the hand and arm take a portion of such water from the bottom and cause it to be projected outside of the boat.

Various types of devices other than pumps have been employed to get water out of boats. All of these devices, however, have embodied a receptacle for receiving the water first and then lifting it out of the boat and discharging it by inverting the receptacle. Such a method of bailing out a rowboat is ineffective and produces unsatisfactory results. Also it is very apt to wet the person using such a receptacle.

It is a particular object of my invention, therefore, to provide a boat bailer which has an interior chamber so curved in relation to the handle that a sweeping movement of the bailer along the bottom of a boat where water is found will have the effect, in a single movement, of gathering up the water and causing it to be thrown from the boat without the necessity of inverting the bailer.

The full objects and advantages of my invention will appear in connection with the detailed description hereinafter to be given and the novel features by which the particular advantageous results from the use of the implement are obtained will be particularly pointed out in the claim.

In the drawing illustrating an application of my invention in one form:

Fig. 1 is a side elevation view of my boat bailer.

Fig. 2 is a longitudinal sectional view taken down the center of the boat bailer.

Fig. 3 is a transverse sectional view on line 3-3 of Fig. 2 viewed in the direction of the arrows.

Fig. 4 is a transverse sectional view of the boat bailer viewed in the direction of the arrows, taken on line 44.

As illustrated the body of the bailer is preferably made of wood. This comprises a main body portion H] which extends into a handle II, connected with the main body portion at an angle indicated at l2 which is only slightly at variance with the general direction of the top edges of the main part l3 and I4 of the boat bailer. These edges, as clearly shown in Figs. 1 and 2, have a broad upward curve indicated at in Fig. 2, and this curve sweeps inwardly at I6 and H,

Fig. 3, to join the handle II as indicated at I 8 and I9. The curved portions 13 and M of the body 10 unite in a front curve 2|] of a broad sweeping character so as to leave a broad lifted toe 2| at the front of the bailer having a bottom curve 22, Figs. 1 and 2, which lifts quite sharply at the front of the bailer but extends into a comparatively flat bottom portion 23. The bailer is thinnest between the toe 2| over the fiat portion 23 as indicated at 24. It thickens substantially on the curve up to the handle I l as indicated at 25, the thickened portion extending into the handle I l. The cavity or chamber 26 within the forward part of the boat bailer has longitudinal and transverse curvature as indicated in Figs. 2, 3 and 4, and this curvature is very important in rendering the appliance capable of accomplishing the results which it does accomplish. It will be noted that up the center longitudinally there is a short curve 21 at the front, a long very slightly curved portion 28 extending from the curve 21 to a point 29 where the chamber curves inwardly and upwardly to the handle as indicated at 30, the upward curve being an easement curve in something the manner of a segment of a logarithmic spiral. Transversely, as indicated in Fig. 3, the chamber 26 has a central flatly curved portion 3| and sharper uplifted curves 32 and 33 on each side thereof. Toward the front of the implement, however, a flat substantially continuous curve 34 is provided.

The advantages of this construction and the results of its use are as follows: When the boat bailer is moved along the bottom of the boat either lengthwise of the boat or across it the lower toe end 2| of the bailer with its curve 22 contacting the bottom will move through the body of water, the curve 22 preventing the implement from catching or tending to injure or mar the boat bottom. The water will move in a body over the curve 2'! and up the bottom portion 28, 29 and at the curve 30 will be caused to curl back as the movement continues, with the implement turned downwardly, and the charge of water picked up by the implement in this manner will be discharged cleanly in a body over the side of the boat. This movement can be repeated rapidly with very little effort with the result that any body of water in a boat, such for example as results from rainfall, will be quickly and thoroughly removed.

Applicant conducted quite considerable experimentation and built a considerable number of bailer structures before she discovered the particular form that would accomplish this clean and certain lifting action. The earlier attempted devices were not successful in that they did not get the desired results, but when the form of this application was finally evolved applicant found that the implement operated with great efliciency and produced really surprising results.

The construction will preferably be of wood which is a cheap and available material and has the advantage of being easily shaped, has great durability, resists wear and is non-injurious in its contacts with the inside of the boat.

I claim:

A boat bailer comprising a unitary structure embodying an elongated body portion formed with a bottom flatly curved on the outside along the central portion and having a progressively increasing transverse inside curvature from toward the point to toward the handle portion thereof with the inside thereof continuously curved both longitudinally and transversely, the bottom wall being progressively thickened from the front thereof to the handle portion, a handle in the longitudinal center of said body portion continuing from the thickened part thereof, the front end being curved upwardly and the rear part bein more broadly curved to continue into the handle, and the outside bottom along its longitudinal center extending from said upwardly curved front end to the upwardly curved and thickened rear part in a substantially straight line.
